Analysing co-articulation using frame-based feature trajectories
(Pattern Recognition Association of South Africa and Mechatronics International Conference, 2010)We investigate several approaches aimed at a more detailed understanding of co-articulation in spoken utterances. We find that the Euclidean difference between instantaneous frame-based feature values and the mean values ... -
Analysing the porous structure of packed beds of spheres using a semi-analytical approach
(Elsevier, 2019)In this paper methodologies are described for the analysis of the porous structure of cylindrical and annular packed beds consisting of spheres when the coordinates and sizes of the spheres are known. Methodologies to ... -
Analysing two control methods of shunt active filters for unbalanced load
(Nagpur: Yeshwantrao Chavan College of Engineering, 2014)A three-phase shunt active filter is used for current and/or voltage unbalance compensation. Two control schemes with two different theory, instantaneous power theory and Generalized Fryze are considered to compensate the ... -
Analysis of a 405 km transmission line with series compensation
(EE Publishers, 2012)This paper presents an investigative case study and energy efficiency analysis of the 405 km, 420 kV transmission line between Insukamini substation in Bulawayo in Zimbabwe and the Matimba thermal power station in South ... -
Analysis of metal-laden water via portable X-ray fluorescence spectrometry
(Elsevier, 2018)A rapid method for in-situ elemental composition analysis of metal-laden water would be indispensable for studying polluted water. Current analytical lab methods to determine water quality include flame atomic absorption ... -
Analysis of PM transverse-flux outer rotor machines with different configuration
(IEEE, 2017)This paper presents the electromagnetic analysis of two permanent magnet transverse-flux outer rotor machines with and without magnetic shunts. The research started with designing and analyzing a permanent magnet transverse-flux ... -
Analysis of reaction mixtures of perhydro-dibenzyltoluene using two-dimensional gas chromatography and single quadrupole gas chromatography
(Elsevier, 2018)Energy storage via liquid organic hydrogen carrier (LOHC) systems has gained significant attention in recent times. A dibenzyltoluene (DBT) based LOHC offers excellent properties which largely solve today's hydrogen storage ... -
Analysis of reference ranges of total serum protein in Namibia: clinical implications
(MDPI, 2020)A reference range is an essential part of clinical laboratory test interpretation and patient care. The levels of total serum protein (TSP) are measured in sera to assess nutritional, liver, and kidney disorders. This ... -
Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009)This paper discusses the numerical analysis of the porous structure of an annular packed bed. Numerical procedures are described to determine the variation in the porosity, the variation in the coordination number (measure ... -
Analysis of the post-earnings announcement drift anomaly on the JSE
(Taylor & Francis, 2013)The post-earnings announcement drift anomaly has been widely researched and confirmed for several markets around the world. This paper investigates the relationship between the earnings surprise as reflected by the price ... -
The Analysis of the Sepedi-English Code-switched Radio News Corpus
(UP Jornals, 2022)Code-switching is a phenomenon that occurs mostly in multilingual countries where multilingual speakers often switch between languages in their conversations. The unavailability of largescale code-switched corpora ... -
An analysis of the slow compression breakage of coal using microfocus X-ray computed tomography
(Taylor & Francis, 2015)The degradation of coal and the production of coal fines during handling and transport is a serious problem in processes that depend on closely sized large particles. To minimize the production of fines, a fundamental ... -
The analysis of voltage and current unbalance by application of active and reactive power in the fundamental frequency negative-sequence components
(IEEE, 2012)The behaviour of the fundamental frequency negative-sequence power components in unbalanced power networks is evaluated for possible information on the relative contribution by the supply and loading network. Previous ... -
Analysis of waveforms in modern power systems
(Wiley, 2008)This chapter contains sections titled: Frequency Analysis of Non-Sinusoidal Waveforms: Practical Considerations; Analog-to-Digital Conversion; Sequence Component Analysis; IEEE 1459: Power Definitions for modern Power ... -
The applicability of an existing fluted tube condenser model when used with refrigerant R-407C
(Elsevier, 2013)Fluted tube-in-tube condensers are key components in energy efficient water heating heat pumps. Rousseau et al. (2003) developed a model that incorporates all the essential features of these heat exchangers. A feature ... -
Application of data analytics to transport corridor diagnostics and performance benchmarking
(IEEE, 2018)Increase in exports is essential for economic growth in developing countries. In Southern Africa the development of effective multi-national trade corridors is the single biggest stumbling block to achieve this objective. ... -
Application of exergy-based fault detection in a gas-to-liquids process plant
(MDPI, 2019)Fault detection and isolation (FDI) within the petrochemical industries (PCIs) is largely dominated by statistical techniques. Although a signal-based technique centered on exergy flows within a process plant was proposed, ... -
